Shoot. (1) Taking a photo. (2) What you say when you don't have a Nikon S9700.
You're capturing a moment in time, but TIME WAITS FOR NO ONE. Sorry, time waits for no one. So if you want that photo of your dog staring down a butterfly, or your baby about to stand up under their own power, or a Traxcheon Death Starship about to explode after being hit by a phantac laser from across the galaxy, you've got to be able to point and shoot NOW. Sorry, now.
If you miss it, you've got a dog chasing a blur, or a baby tipping over, or a pile of flaming Traxcheon goo burning a hole in your garage due to the acidic nature of their biochemical makeup. DON"T LET THIS HAPPEN--wow sorry, don't let this happen to YOU.
